Hence, each message \(W_{{\mathcal {J}}}\)  where \({\mathcal {J}}\in {\mathcal {T}}_{\lbrace 1,2,3,4\rbrace }\)  can be recovered by the users in \({\mathcal {J}}\) . In general, we transmit the codewords for \({\mathcal {T}}_{{\mathcal {B}}}\)  through the relays \({\mathcal {B}}\)  such that each user in \({\mathcal {J}}\)  can recover \(W_{{\mathcal {J}}}\)  where \({\mathcal {J}}\in {\mathcal {T}}_{{\mathcal {B}}}\) . The link-load to transmit \({\mathcal {V}}_{1}\)  is \(2/5\)  such that the link-load of this scheme is \(3/5+2/5=1\)  while the link-loads of the scheme in Section , in [1]}, [2]} and [3]} are \(6/5\) , \(9/4\) , \(3/2\) , and \(3/2\)  respectively.
